Trichostrongylus is important in stronylidae because of food animals. Trichostrongylus species are nematodes (round worms), which are ubiquitous among herbivores worldwide, including cattle, sheep, donkeys, goats, deer, and rabbits. At least 10 Trichostrongylus species have been associated with human infections. Infections occur via ingestion of infective larvae from contaminated vegetables ...

The cyathostomum is the smallest of the strongyle. It is a genus of small strongyle nematodes that have been variously divided into a number of genera and subgenera. Approximately 40 species affect horses and elephants, colonizing the cecum and colon; results in weight loss, hypoalbuminemia and diarrhea. The small strongyles include 40 or so species that commonly infect the cecum and colon of ...

The final host of Aelurostrongylus abstrusus is cats. The male measures 7.5 mm and the female 9.9 mm. Males have a short bursa and the vulva of the female opens near the posterior end. Adult female worms lay their eggs in the alveoli of the cat's lung. The eggs hatch and the first stage larvae (L1) are carried up the trachea, swallowed and pass out with the feces.
The L1 can live for ...

The paratenic host of Aelurostrongylus abstrusus is rodents and lizards. Cats are more likely to be infected by eating the paratenic hosts as snails and slugs are usually not part of their diet. The L3 will penetrate the gut wall and migrate through the peritoneal and thoracic cavities to the lung.
The larvae will develop to the adult stage and egg laying will begin 5 to 6 weeks after ...

The infective stage of ostertagia is L3. The species within the subfamily Ostertaginae form a large and complex group, the taxonomy of which has not been fully elucidated, and is constantly under revision. O. ostertagi adults are slender reddish-brown worms. Adult males measure 6-8mm, adult females 8-11mm, and the eggs measure 70-86μm in length.
Identification of adult medium ...

Adult whipworms are found in the large intestine. Infection occurs through ingestion of eggs and is more common in warmer areas. Whipworms eggs are passed in the feces of infected persons, and if an infected person defecates outside or if untreated human feces as used as fertilizer, eggs are deposited on soil where they can mature into an infective stage.
Ingestion of these eggs "can ...

In order to treat heartworms you can use an arsenic derivative, bed rest and leash walking. Dirofilaria immitis, the heartworm or dog heartworm, is a parasitic roundworm that is spread from host to host through the bites of mosquitoes. The heartworm is a type of filarial worm, a small thread-like worm that causes filariasis. The definitive host is the dog, but it can also infect cats, wolves, ...

Morulated is the term for the appearance of the ova of ostertagia. A morula (Latin, morus: mulberry) is an early stage embryo consisting of cells (called blastomeres) in a solid ball contained within the zona pellucida. A morula is distinct from a blastocyst in that a morula (3–4 days post fertilization) is a 16-cell mass in a spherical shape whereas a blastocyst (4–5 days post ...

Stercoralis is the species of the man and dog strongylid. The strongyloid's life cycle is heterogonic—it is more complex than that of most nematodes, with its alternation between free-living and parasitic cycles, and its potential for autoinfection and multiplication within the host. The parasitic cycle is homogonic, while the free-living cycle is heterogonic.
The heterogonic ...

Aelurostrongylus abstrusus is the scientific name of the cat lung worm. This is an indirect lifecyle, involving two intermediate hosts, and a definitive host. The female is ovo-viviparous, and passes L1 within the host faeces. The L1 then infect the molluscs, and later develop into L2, then infective L3. The paratenic host ingests the molluscs.
The cat, acting as the definitive host ...
